WICK TYPE OIL BURNER Filed March l2, 1947 Patented Dec. 5, 1950 UNITED STATES PATENT OFFICE WICK TYPE OIL BURNER 1 Claim.

This invention relates to a wick including oil burner.

The chief object of this invention is to provide an elcient oil burner of but few parts that can be incorporated in a new heating unit such as a stove or .furnace or may be included in an old unit of that character, as desired or required.

Since the latter vary greatly the present disclosure is limited to the burner per se, and a suitable support or base utilized when desired or required. Since fuel supply control, ignition, etc., may be of various types old and well known in the art of oil burner equipment, the disclosure is similarly restricted to the burner unitr and its supporting base if, as and when described.

The chief features of the present invention resides in a burner unit including a peripheral rim terminating at an elevation appreciably above the upper face of the interior or well portion of such unit, the latter having air supply ports therethrough contiguous to fuel supply troughs therein, the latter being adapted to nest substantially coextensive Wick means, said Wick means terminating above said upper face.

Other objects and features of the invention will be set forth more fully hereinafter.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims:

In the drawings Fig. 1 is a top plan View of a circular form of burner and base embodying the invention.

Fig. 2 is a longitudinal sectional view thereof taken on line 2-2 of Fig. 1 and in the direction of the arrows.

Fig. 3 is a top plan View of a rectangular embodiment of the invention.

Fig.'I 4 is a longitudinal sectional view taken on line 4-4 of Fig. 3 and in the direction of the arrows.

Fig. 5 is a transverse sectional View taken on line 5-5 of Fig. 4 and in the direction of the arrows, the wicks being omitted.

In Figs. 1 and 2 of the drawings I0 indicates the bottom of an air chamber type base, herein provided with bearing feet or the like I, the` peripheral circular wall I2 rising from the bottom, the side walls I3 coplaner therewith and end wall I4 of the throat structure, the upper elevation thereof being below the elevations of walls I2 and I3, as shown in Fig. 2 thus forming a restricted throat |4a.

The burner proper includes main body portion I5 provided with extension I6. The former is dened by upwardly directed circular rim I1 and opposed thereto is the reduction or groove I B, the latter being continued at I9 upon both sides of extension I6.

Arranged concentrically are the annular series of arcuately spaced elongated air passages 20 and 2 I. Same may have an arcuate length conformation. Disposed centrally are other air passages 22.

Between the central portion 23 and the rim Il and between the several air passages are the two circular fuel troughs 24 and 25, shouldered as at 24a and 25a respectively. In said troughs and in the lowermost portions thereof are nested the lower ends of annular wicks 26 and 21. Note that the upper portions of said wicks project above the upper face of body portion I5 and herein are shown as terminating in the plane of the top edge of rim I1. The `mid-portion of each wick is shown spaced from the adjacent walls of the groove. This permits air to flow into same and follow up the adjacent surface of the wick.

The inner or central passages 22 supply air to the inside face of wick 21. Passages 20 supply air to the outside face of wick 26 while passages 2| supply air to the inside face of wick 26 and the outside face of wick 21.

Coextensive with the extension I6 and extending radially into body portionY I5 is the fuel supply tube 28 that discharges fuel at 29 and 30 to troughs 24 and 25, respectively.

Reference will now be had to the rectangular form of the invention. While shown elongated in the same general direction as shown in the prior form, it may be provided with additional troughs and air passages and thus be wider than it is long.

Such variation requires no illustration, being an obvious modiiication of the form now to be described. y

In Figs. 3 to 5, |||l indicates the bottom of the base unit, I I2 the end wall, I I3 the side walls, and ||4 the lower front wall. The burner body portion ||5 includes extension H5 and coextensive therewith is fuel supply conduit |28 having transverse branches |29 and |30 sealed at opposite ends. lThese branches are disposed at the front ends of troughs |24. Each branch opens or discharges at I 29a and |302, respectively. |I4a indicates a restricted throat.

The body portion includes rim I I1. The

troughs |24 are shouldered at |248L and said troughs herein are spaced apart and substantially parallel and coextensive with the bottom portion ||5 from nearly rim to rim. In each trough is nested the wick |26.

The several wicks may be and preferably are of the asbestos type.

Included in the body portion between the rims and the troughs parallel thereto are the aligned, elongated, linearly spaced series of air passages |20, Between the troughs are a similar set of passages I2I, |22, thus numbered because functionally they fulfill the purposes fulfilled by passages 2l and 22 in the iirst embodiment.

As before, the body portion H5 is shouldered or grooved as at H8 and extension H6 is shouldered or grooved as` at I i9. In both forms of the invention the burner-base combination has the extension of the base terminating rearwardly of the front wall of the base and said front wall terminates below the bottom level of the body portion. This provides a restricted mouth to the throat of the resulting air chamber. The base serves as a catch basin for surplus fuel oil in the event of accidental ilooding due to control failure.

While the invention has been illustrated and described in great detail in the drawings and foregoing description, the same is to bev considered as illustrative and not restrictive in character.

The invention claimed is:

A burner having a main body, a tray type base having an outline substantially corresponding to that of the body, an extension on, each, the base extension projecting beyond the body extension and forming at the remote ends thereof a throat with a restricted mouth for air supply, the body being supported on the base to form a cover for the same and an air supply chamber therewith, an upstanding rim upon and defining the outline of the body, walls in said body forming a plurality of fuel supply troughs, samel bei-ng substantially equidistant from each other; said' body having a plurality of sequentially spaced air passages extending therethrough and disposed between each pair of troughs, certain of said air passages being disposed between the rim and the trough closest thereto, the inner side walls of each trough having a lateral shoulder spaced between the top and bottom of the trough for exposure of the mid-portions of the opposite sides of the wick, and a wick seated in the bottom of each trough and extending upwardly toward the top thereof and terminating above the level of the adjacent shoulders and approximately in the plane of the top edge of the rim.
